Zinc phosphate (Zn3(PO4)2) is an inorganic chemical compound used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead). It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor. Zinc phosphate coats better on a crystalline structure than bare metal, so a seeding agent is often used as a pre-treatment. One common agent is sodium pyrophosphate.

INTRODUCTION
Zinc phosphate, as a new generation of antirust pigment, is a new type of nontoxic and harmless white antirust pigment with excellent performance in rust prevention and ideal application effect. It is the best substitute of conventional antirust pigments containing heavy metals such as lead and chrome.Zinc Phosphate renders coating materials excellent rust-preventing performance and good resistance to water
END APPLICATION
•Zinc Phosphate is used in corrosion resisting primers and undercoats.It is widely used in various coating materials for preparation of waterproof, acid-resistant or corrosion preventive coating materials such as phenolic paint, epoxy paint, acrylic paint, paste paint.
Zinc Phosphate is used in manufacturing of Zinc Rich Paint Formulations.
Zinc Phosphate is used manufacturing of Fertilizers.
•Zinc Phosphate is used for water-soluble resin paint in the fields of shipbuilding, automobile, industrial machinery, light metal, household appliances and metal containers for foods.
